For years, carriers have been charging consumers with massive global data roaming fees.

Adam Savage, former co-host of Mythbusters, was given a $10,000 bill by AT&T for his trip to Canada. A Chicago Bears fan watched his team play while on a cruise ship on the AT&T network and it cost him nearly $28,000. A Portland family got a $20,000 bill from AT&T after he used an AirCard while traveling into Canada.
